Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Periodontal health can be considered to be in a state of balance when the bacterial mass presents in the host oral cavity and causes no damage to either the bacteria or the host periodontal tissues. Any disruption of this balance results in alterations in both the host periodontal and biofilm bacteria and leads ultimately to destruction of the periodontium. Accumulation of dental plaque may lead to several harmful effects on the tooth and tooth supporting periodontal tissue that contributes to the development of caries and periodontal diseases. Therefore, an effective dental plaque control is essential for maintaining good oral hygiene.
Mechanical plaque control, by using toothbrushes and interdental aids, is the mostly adopted method. Unfortunately, it is a time consuming process and needs high manual dexterity. Moreover, epidemiological studies revealed high prevalence of gingivitis among toothbrush users. Hence, chemical plaque control may be used to assist in dental plaque control.
The anti-plaque agent is that agent that interferes with one of the different phases of dental plaque development: interferes with the adhesion of oral bacteria to oral surfaces and prevent biofilm formation; interferes with co-aggregation mechanism which thereby prevents future growth of micro-colonies; or removes or disrupts existing dental plaque. To date, chlorhexidine (CHX) mouthwash is the standard solution used in chemical plaque control, but it was found to have several side effects including tooth and some restorations staining, unpleasant test, sloughing of oral mucosa and enhancement of supra-gingival calculus formation.
The widely available traditional natural medicinal plants can be utilized as stable, safe and biologically active plant-derived galenicals as alternative to synthetic drugs. Among these plants, Salvadora persica L. (Sp) root sticks and green tea (Gt), leafs of Camellia sinensis. Kuntze, aqueous extracts were reported to have anti-microbial activity against many oral bacteria. In our in vitro study, we found that the combination (Co.) of 0.25mg Gt aqueous extract and 7.82mg Sp aqueous extract in 1ml exhibited significant synergistic anti-bacterial and anti-adherence efficacy against primary plaque colonizers.
The dental plaque is classified into two categories, supra-gingival plaque and sub-gingival plaque, in relation to gingival margin. The supra-gingival dental plaque may be readily visualized on teeth after 24 to 48 hours with no oral hygiene measures and it appears white, grayish, or yellow in color and has a globular appearance.
Supra-gingival plaque accumulation on tooth surfaces can be quantified through different plaque index systems. In this study, the clinical parameter to record plaque quantity was modified Quigely Hein Plaque Index. In this index, a score of 0 to 5 was assigned for each facial and lingual (palatal) surface of all teeth except the third molars.
